Very nice gameplay loop, and one crazy background story too.
The game seems huge. Well done for cramming so much quality content in a game jam entry. I wasn't able to get to the end as I got stuck in one area and couldn't figure out how to proceed. Nothing to do with the game, I'm just not good at puzzles :)
As others already mentioned, some background music would have taken the atmosphere to the next level.
Overall very well done!
